Patella-tibial suture [equally developed
on all legs – see Anteropatellata (1)] goes by anterior (dorsal) side of tibia exactly along tibia
and has a form of light line on dark background; distally from the middle
of tibia this suture has its usual oblique direction (Kluge
& Novikova 2014: Fig.67–68). In Baetodes/g3 it undergoes further
modification [see below, Baetodes/g3 ()].

Non-unique
autapomorphies
of Baetodes/g2.

() Larva is
adapted to inhabit in rapid waters, with this are connected some
unique apomorphies [see ()–()], as well as non-unique ones: body
Acentrella-like, i.e. with flattened ventral and convex dorsal side, thorax
relatively large in comparison with abdomen (non-unique character – see
Index of characters [1a]);
paracercus is vestigial, consists of several segments (non-unique character
– see Index of characters [1.3.64]); cerci
are long, swimming setae are short or
lost.
